FRITZ MULLER, OF DARMSTADT, GERMANY.

GAS-PRODUCER.

Specification of Letters Patent.

Patented Aug. 17, 1909.

Application filed December "I, 1906. Serial N 0. 346,766.

To all whom it may concern:

.Be it known that I, FRITZ MtiLLER, engineer, subject of the Emperor ofGermany, residing at Darmstadt, Grand Duchy of Hesse, Empire of Germany,have invented certain new and useful Improvements in and Relating toGas-Producers, of which the following in a specification.

In the accompanying drawings forming part of this specification, Figure1 is a vertical sectional view of a gas generator embodying myinvention. Fig. 2 is a similar view taken on a line substantially atright angles to the section line of Fig. 1.

in order to be able to produce gas from ve wet fuel in gas producerswit-h combustion above and below, arrangements must be adopted, whichallow of a portion of the water being expelled from the fuel before itcomes within reach of the upper Zone of combustion, as otherwise theupper fire would be put out by the water in the fuel.

My invention consists generally in various constructions andcombinations, all as hereinafter described and particularly pointed outin the claims.

For this object by the present invention a hollow body (1 provided onall its free sides with openings or apertures, or formed as a grate ofseparate bars, is constructed above the upper fire, which body acommunicates at its ends with the external air and the sur faces ofwhich so steeply inclined that the fuel cannot remain sticking on it butmust slide down its walls. External air enters into the hollow body aand also gases of combustion derived from the upper fire, so-that thelast named are burned in the hollow body (a. The water is partiallyexpelled from the downwardly sliding fuel lying above and at the side ofthe hollow body, by the heat resulting from this combustion. In the caseof very large gas producers several of these hollow bodies may beemployed. An opening D is provided in the side wall of the generator,through which the manufactured gas may escape. The watery vapor givenoff from the fuel may be conveyed in the ordinary way through passagesor flues Z) to the under fire or'when it is formed in too largequantities, allowed to escape into the open air through the chimney c.

I declare that what I claim is 1. A gas generator, comprising an uprightreceptacle and a grate 1n the lower part thereof, the walls of saidreceptacle at its upper and lower ends being contracted and itsintermediate walls being vertical substantially, and a hollow bodyarranged transversely of the generating chamber be tween the middleportion thereof and its upper end and the walls of said body flaringoutwardly from the top toward the middle portion thereof and inwardlyfrom the middle portion toward the bottom thereof, and said walls havingperforations therein, and the interior of said body communicating withair intake ports provided in the walls of said generator, substantiallyas described.

2. The combination, with a gas generator, of a hollow body arrangedtransversely of the generating chamber, the walls of said body beinginclined outwardly from the top toward the longitudinal center of saidbody and inwardly from the center toward the lower portion of said body,and the cues of said body communicating with air intake openingsprovided in the walls of said generator, and the walls of said bodyhaving a series of perforations therein, substantially described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
